With a 35mm-equivalent focal length of 24-76mm, the Pentax SMC DA* 16-50mm f/2.8 ED AL SDM is an ideal zoom for portraiture, event and wedding photography, and general everyday use. The fast f/2.8, nine-blade aperture makes it a great low-light performer, providing smooth bokeh with excellent background separation. The DA* 16-50mm uses two extra-low dispersion elements and three aspherical elements to provide sharp images with very little optical aberration.
It features Pentax’s Supersonic Drive Motor system, which provides fast, silent, and accurate autofocus performance.
As one of Pentax’s DA*-series lenses, the 16-50mm f/2.8 has several key features that set it apart from many other lenses. Since it’s designed for crop-frame APS-C sized sensors, it offers a reduced physical size and weight. It features the DA*-series’ standard fully weather-sealed build, with Pentax’s SP-coating for a dust- and water-resistant front element.
